GREASE-CUP.

To all whom it may concer/n Be it known that I, LLOYD Gr. CoPnMAN, acitizen of the United States, residing at Flint, in the county ofGenesee, State of Michigan, have invented a' new and useful of which thefollowing is a specification.

This invention relates-to grease cups and capsules and has for itsobject a grease cup which is adapted to eject a collapsible capsule whenthe` grease has been used out of the same.' Several ways of gettingV thegrease capsule when it is collapsed, out of the grease cup, have beendevised, which work usually on plunger in retreating out :of the cuppick out the capsule.

The present invention relates to another way and a very eliicient way ofaccomplishing thisl same result.

Figure 1 shows a grease cup with my invention in connection therewith.

Fig. 2 shows the grease cup with the vcup and plunger removed and thespring distended.

Fig. 3 is a similar view showing how, when the grease has been exhaustedfrom the capsule and the plunger removed, the collapsed capsule isejected. v

c designates the grease cup with the usual bodyr portionand nozzleportion b. The top of the cup is externally threaded to receive theusual capc. Through the cap is threaded the plunger stem (l on which isthe plunger e. A collapsible capsule f of the character described insome of my prior -patlents and usually made out of some kind of paper isshown in the grease cup. 'The contents of the capsule pack or collapsethe spring g when the same is inserted and the cap screwed down. Thisiswell shown in Fig. 1. The normal position of this spring is adistended one, as shown in Fi 2.

Now obviously'when the capsu e has expelled practically. all 4of itscontents by reason of the pressure brought to bear upon it by theplunger e and when the plunger is Specification of Letters Patent.

withdrawn, the spring g rises and the plunger and at the same timecarries up the collapsed capsule f so that it is either completelythrown out by the spring or else raised to the position shown in Fig. 3,where it may be easily grasped by the fingers and thrown away. The lowerend of the spring may be soldered or otherwise fastened to the end ofthe body portion of the cup as at h.

This simple expedient serves to avoid the necessity of using someinstrument to pick the capsule out of the grease cup when the grease hasbeen expelled from it.

What I claim is:

1. A grease cup for holding a collapsible capsule, a cap therefor, aplunger or follower for said cup, and means located in the grease cupfor expelling a collapsed capsule when the plunger and cap are removed.

2. In a devicev for the purpose specified,

- thecombination of a grease cup for holding a collapsible capsule, a catherefor, a plunger or follower, and col apsible,

able means for expelling a collapsible grease moved. v

.3. In a device for the purpose specified, the combination of a greasecup for holding a collapsible capsule, and collapsible, yieldable meanslocated within the cup portion of the grease cup for expelling acollapsed capsule when the cup is opened up.

, 4. In a device for the purpose specified, the combinationiof a greasecup for hold'- ing a collapsible capsule,y and a collapsible springlocated in the grease cup for ejecting a collapsible capsule when thecup is opened.

5. In ,a device for the purpose specified, the: combination of a greasecup for holding a collapsible capsule, a cap therefor, a plunger. endfastened to the bottom of the grease cup and acting to expel acollapsible capsule when the plunger and the cap are removed.

In witness whereof I have hereunto set my hand on the 29th day ofOctober, 1917.
